What is the similarities between suspension and colloid? both are heterogeneous mixture. particles of both suspension and colloidal solution scatter when a beam of light is passing through them and make it’s path visible. How do you identify suspensions colloids and solutions? In summary: A solution is always transparent, light passes through with no scattering […]

Has there ever been a Shinkansen accident? The Shinkansen, Japan’s high-speed rail line, has never had a fatal crash or derailment in its 55-year history. (One train hit a man on an elevated track last year in what the police described as a suicide.) Is the Shinkansen profitable? Not all Shinkansen are profitable, but four […]

What are the 4 major functions of muscles? Terms in this set (7) four main functions. movement, maintenance of posture, heat production, joint stability. movement. locomotion, blood circulation, food digestion. uses all three types. blood circulation. smooth muscle. food digestion. posture maintenance. heat production. joint stability. What are the 3 tissue types? There are 4 […]

Does light travel faster in air or glass? Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. How does a black hole attract light if it […]

How can I see my house from satellite? To see a satellite view of your house: Use the search field in the top left to enter your street address. You’ll see your address in the search results. Zoom in closer to get a detailed overhead satellite view of your home. You can drag the man […]

Who gave wave theory of light? Christiaan Huygens What did Newton do with two prisms? Intrigued by the change in shape, Newton cut a variety of holes of different sizes and shapes, but no matter the shape of the original beam, the refracted light turned more oblong. Newton also placed a second prism of the […]

What is the measure of the radius of the circle? Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of […]

What happens when the cross product of two vectors is 0? If two vectors have the same direction or have the exact opposite direction from one another (i.e., they are not linearly independent), or if either one has zero length, then their cross product is zero. When two non-zero vectors A and B are perpendicular […]

What are the 3 main nutrient cycles in an ecosystem? The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life. What is a […]

How do you collect data for experiments? Recall that data can be collected in two main ways: (1) through sample surveys or (2) through designed experiments. While sample surveys lead to observational studies, designed experiments enable researchers to control variables, leading to additional conclusions. What is the most reliable method of collecting data? Here are […]
